Question

3. Officials from the county and Envy City have asked you to look into the share they contribute and receive. The current tax rates are 4.9 percent state and 1 percent local. Based on the tax rates in effect for each given year, the table below presents annual collections for the state retail sales tax in the county, the county retail sales tax, the county's share of the county retail sales tax, and Envy City's share of the county retail sales tax. Note that the differ- ence between the county total and the county share and the city share is the amount distributed to smaller jurisdictions in the county. Estimate revenues for each of the jurisdictions for years 16 and 17 using any method that is ap propriate.

Explanation / Answer

Using Excel, we can analysis the regression model and give the output as follows

The regression model is

R = 92394498+ 11226365*T

to estimate revenues for years 16 and 17 is

R = 92394498+ 11226365*16 =272016338

R = 92394498+ 11226365*17= 283242703
